Primer: How to Use RBAC for Applications to Control App Use of the Mail.Send Permission
The temptation to use the Mail.Send application permission in scripts can lead PowerShell developers into trouble because the permission allows access to all mailboxes, including sensitive executive and financial mailboxes. Fortunately, RBAC for Applications allows tenants to control the access that apps have to mailboxes and other Exchange content. All explained here with an example script to test RBAC of Applications. https://office365itpros.com/2026/02/17/mail-send-rbac-for-applications/
Cross forest Distribution Group list expansion
We have two forests in a 2-way trust. On each forest there's an Exchange 2016 Organization installed. On one forest a Distribution group has been created with users from both the forests, in ADUC we see the membership correctly for all the users. On the Exchange Console of that Forest opening the DG we can see only the "local" users and the SID for the remote one. Sending an email to the DG it only delivers to local forest's users. Why Exchange Server doesn't expand the DG membership as the ADUC does and deliver emails to all recipient ? Do we have to replicate remote Forest's Users as local contacts ? thanks
Hidden Group and Hidden Group Membership
Hi everyone! I have come across a requirement where the client would like to use an excel spreadsheet, a service account and application registration to manage group membership for a confidential group. They would like to create a group from which the members cannot leave, see other team members and cannot see the group itself. Now, I have the concept of the flow with me but for the life of me, I cannot get around to finding/configuring a group that meets the requirement. Have you guys come across this sort of scenario? Group Configuration: Users should not be able to view the group Users should not be able to view members of the group Users should not be able to leave the group Thanks in advance.
Collect count of emails sent to ALL Distribution Groups in ExOL
Hey Team, I am looking for PowerShell assistance, such as exporting a list of all distribution groups and measuring how many messages were sent to each DG in the past 10 days. Basically, how can I combine "Get-DistributionGroup -ResultSize Unlimited | Select-Object Name, DisplayName,GroupType,PrimarySmtpAddress | Export-csv c:\temp\DistributionGroupReport.csv -NoTypeInformation" and "Get-MessageTrace -StartDate (get-date).AddDays(-10) -EndDate (Get-Date) -RecipientAddress email address removed for privacy reasons | measure-object | Select Count" to a single csv, if possible. Thanks.

How to share contact groups now in Office365 as 'Public Folders' don't show in New Outlook
I have used contact lists in 'Public Folders' for a team of users for many users, now users on NEW OUTLOOK cannot use or see these. What do I use now to import these contact lists (csv or whatever) into what medium on Office365, a shared mailbox, a public folder mailbox, a distribution list, contact group, M365 group to hold all these lists for different clients? Note: All users should have the ability to edit the contact lists AND send email (like its an Outlook Address Book). It must be mail-enabled as the users just need it to send emails to.

Dynamic Distribution Group User Exclusion Recipient Filter
I have a dynamic distribution group that uses Office locations for its recipient filter. It is able to pick up all of the users needed, however, there are a few service accounts I want to exclude from the dynamic group. I know the easy answer is to remove the Office info from the service accounts, however I'd prefer not to. As I'm using this example as a test for excluding users from future dynamic distribution groups that we're going to be migrating to exchange online. Here is an example of the recipient filter in use: $filter = "((Office -eq 'Spokane, WA') -or (Office -eq 'Sandpoint, ID') -and (RecipientType -eq 'UserMailbox') -and (RecipientTypeDetails -eq 'UserMailbox')) -and (-not(UserPrincipalName -like 'email address removed for privacy reasons' -or 'email address removed for privacy reasons')))" The service accounts still appear in the dynamic group's recipient list.
